Estado de Conservación y cobertura vegetal de la vereda Busaga (Iza - Boyacá)

Se presentan los datos estructurales de la cobertura vegetal perteneciente a una franja altitudinal de bosque alto andino (2800 a 3200 msnm) en la vereda Busagá (Iza – Boyacá). Se realizo fotointerpretación (ArcGIS 9.0) que arrojan 6 unidades de cobertura vegetal: bosque nativo, matorral alto, matorral bajo, matorral rosetoso, bosque plantado y pastizales 1 y cultivos, con su respectiva verificación. La caracterización fisionómica y florística de las especies arbóreas, arbustivas y herbáceas reportan 58 especies pertenecientes a 26 familias, 23 ordenes y 47 géneros. El hábito de crecimiento más representativo es arbustivo (46,5 %). Las especies dominantes son: Vallea stipularis, Morella parvifolia y Viburnum tinoides. La unidad vegetal con mayor área de cobertura son los pastizales y cultivos seguida de los parches de bosques nativo y matorrales altos; los cuales guardan elementos asociados a comunidades vegetales nativas, pero reflejan el alto grado de intervención antrópica y fragmentación que existe en la zona

MONITOREO DE CADMIO Y PLOMO EN TEJIDOS DE Turdus fuscater EN SOGAMOSO (BOYACÁ-COLOMBIA)

En el valle de Sogamoso las actividades siderúrgicas son la fuente principal de contaminación ambiental, donde se destacan emisiones de material particulado compuesto principalmente de metales pesados. Sin embargo, no existe información sobre la bioacumulación de metales pesados en aves de la región, lo cual es aceptado como una medida indirecta de la presencia de estos materiales tóxicos en el ambiente. Para ello se realizó una fase de campo, seguida de una de fase de laboratorio, con el propósito de determinar la concentración de plomo y cadmio en tejidos de hígado, pulmón, riñón, bazo y cerebro de Turdus fuscater (Aves:Turdidae). Se encontró la presencia de plomo y cadmio en todos los tejidos. Estos resultados, serán usados como línea base para evaluar la contaminación con metales pesados en aves silvestres en el corredor industrial del Departamento de Boyacá. Las muestras fueron tratadas mediante digestión ácida y la concentración de los metales determinada por espectroscopía de absorción atómica utilizando Horno de Grafito. El límite de detección y de cuantificación para plomo fue de 0.00108 ppm y 0.00291ppm, respectivamente. Mientras que para el cadmio fue 0.01669 ppm y 0.03898 ppm, respectivamente. El grado de recuperación, para ambos metales, fue superior al 90 %. El patrón de acumulación en peso húmedo de cadmio fue: hígado 4.32± 0.53 ppm, pulmón 3.74±1.12 ppm, riñón, 3.97±1.08 ppm, bazo 3.38±1.01 ppm y cerebro 2.9±1.0 ppm, lo que sugiere que las aves silvestres están siendo expuestas a concentraciones de estos elementos en el ambiente. Con la información obtenida se sugiere que la especie Turdus fuscater (T. fuscater), es idónea para programas de biomonitoreo ambiental, lo cual permite realizar proyecciones sobre el deterioro de este hábitat.Palabras clave: altiplano cundiboyacense, siderurgia, metales pesados, biomonitoreo, aves.

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

ENGIU: Encuentro Nacional de Grupos de Investigación de UNIMINUTO.

El desarrollo del prototipo para el sistema de detección de Mina Antipersona (MAP), inicia desde el semillero ADSSOF perteneciente al programa de Administración en Seguridad y Salud en el trabajo de la UNIMINUTO, se realiza a partir de un detector de metales que emite una señal audible, que el usuario puede interpretar como aviso de presencia de un objeto metálico, en este caso una MAP. La señal audible se interpreta como un dato, como ese dato no es perceptible a 5 metros de distancia, se implementa el transmisor de Frecuencia Modulada FM por la facilidad de modulación y la escogencia de frecuencia de transmisión de acuerdo con las normas y resolución del Ministerio de Comunicaciones; de manera que esta sea la plataforma base para enviar los datos obtenidos a una frecuencia establecida. La idea es que el ser humano no explore zonas peligrosas y buscar la forma de crear un sistema que permita eliminar ese riesgo, por otro lado, buscar la facilidad de uso de elementos ya disponibles en el mercado

Reduction of cardiac imaging tests during the COVID-19 pandemic: The case of Italy. Findings from the IAEA Non-invasive Cardiology Protocol Survey on COVID-19 (INCAPS COVID)

Background: In early 2020, COVID-19 massively hit Italy, earlier and harder than any other European country. This caused a series of strict containment measures, aimed at blocking the spread of the pandemic. Healthcare delivery was also affected when resources were diverted towards care of COVID-19 patients, including intensive care wards. Aim of the study: The aim is assessing the impact of COVID-19 on cardiac imaging in Italy, compare to the Rest of Europe (RoE) and the World (RoW). Methods: A global survey was conducted in May–June 2020 worldwide, through a questionnaire distributed online. The survey covered three periods: March and April 2020, and March 2019. Data from 52 Italian centres, a subset of the 909 participating centres from 108 countries, were analyzed. Results: In Italy, volumes decreased by 67% in March 2020, compared to March 2019, as opposed to a significantly lower decrease (p &lt; 0.001) in RoE and RoW (41% and 40%, respectively). A further decrease from March 2020 to April 2020 summed up to 76% for the North, 77% for the Centre and 86% for the South. When compared to the RoE and RoW, this further decrease from March 2020 to April 2020 in Italy was significantly less (p = 0.005), most likely reflecting the earlier effects of the containment measures in Italy, taken earlier than anywhere else in the West. Conclusions: The COVID-19 pandemic massively hit Italy and caused a disruption of healthcare services, including cardiac imaging studies. This raises concern about the medium- and long-term consequences for the high number of patients who were denied timely diagnoses and the subsequent lifesaving therapies and procedures
